With 12.5 wide tires you will have ZERO problems.

With 13.5" wide tires you will need to make sure your wheels have a little more offset or get wheel spacers. As Well as cranking your Torsion Keys to make some more room. You will still get some light rubbing but this wont cause any harm as it will be on your sway bar.

That is a solid answer.

I had 37x12.5 tires. The truck was fine. I then went to 37x13.5 and had to crank torsion keys to get them to fit. If you have no desire to lift it be sure to go with the 12.5" tires.
